Update git submodules

* Update docs/submodules/releng from branch 'master'
  - [armband] Disable fraser jobs and vping_ssh verify

    - Disabled fraser jobs as we no longer intent to cherry-pick changes to it

    - Now healthcheck includes vping_ssh, so remove it as a dedicated test for
    verifying patches on gerrit to avoid double checking.
